TL;DR: The XANES spectrum of a DNA sample with a known ratio of the polyn nucleotides is equivalent to the weighted sum of the spectra of individual polynucleotides, indicating that the difference in base stacking interactions produces negligible spectral effects.

TL;DR: The high degree of specificity of this technique coupled with the well resolved resonances of various forms of nitrogen provide one of the best methods for differentiating nitrogen chemical forms in fossil fuels as mentioned in this paper.
